SHOE-H EEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,061, dated December 12, 1882.

Application filed October 16, 1882. (No model.)

To all whom it may concern:

Be it known that we, CHARLES KEIGHLEY and AR'LOND H. BLAISDELL, citizens of the United States, andresidents of Vineland, Cumberland county, New Jersey, have invented certain Improvements in Shoe-Heel-Buruishing Machines, of which the following is a specification.

Our invention relates to certain improvements in attachments for shoe-heel-buruishing machines for the purpose of automatically imparting to the shoe holder or jack the movements necessary to carry the heel back and forth under the vibratinglburnishing-tool, the main difference between our invention and that described in the application of Charles Keighley, tiled December 14, 1881, being that in the present case the attachment is so coustructed that it can be readily applied to the machines as now in use, and the devicesfor operating the jack being such that there is a more; effectivej action of the burnishing-tool upon the hollow of the heel than in the former case.

In the accompanying drawings, Figure l,

i Sheet 1, is a side view, partly in section, of a heel-burnishing machine with our improvements gliig?, Sheet 2,' a side view, partly in section, of part of Fig. 1, but looking in the opposite direction; and Fig. 3, an end view of part of Fig. 2, looking in the direction of the arrow.

A is the centralstandard or column of the machine, having at the rear a projecting bracket, B, on which are formed bearings for the drivin g-shatt D, the latter having the usual belt-pulleys, and being furnished with a crank- `wheel, E, the pin of which 4is connected by a rod, E', to the short arm of the lever F. The long arm of this lever carries the toothed segxneut ,which gears into a pinion on the toolshat't G, so that as the lever is vibrated a partial rotary movement will be imparted to said shaft, and the tool will be carried back and forth around the'heel of a shoe clamped in the jack H, the latter being hung to a stud on the front of the machine, so as to be free to vibrate.

In the above -mentioned application of Charles Keighley mechanism was shown which derived its motion from the shaftD ofthe machanges in the machines as built that the alterations could not be readilyeffected in the shops where the machines were located.

'In carrying out our present invention we make no change in the usual machine, except the formation of openings sv in the standard A and a central opening in the stud b, to which the lever F is hung, these openings being adapted for the passage of a rod, d, the front end of which is connected by a link, e, to the shoe-carrying jack H, the rear end of the rod being connected by a rod, f, to a slotted arm, g, which projects from a pinion, h, the spindle of the latter having its bearingin a projection on a frame, m, which is secured to or forms part of a frame, a, bolted to the bracket B of the machine, a further support for the frame m being afforded by a bar, p, which is bolted to the frame and to the stud b.

To bearings on the frame a is adapted a shaft, It, one end of which carries a wormwheel, s, the opposite end of the shaft having a cam-wheel, t, and the shaft being driven by a worm, n, which gears into the worm-wheel s, and is carried by a spindle adapted to bearings on the frame m, said spindle being driven from the shaft D through the medium of a suitable belt.

To the groove of the cam-wheel t is adapted na pin on the lower end of a rack, fw, which engages with the pinion h, and is adapted to suitable guides on the face of the frame m. As the shaft 7c is rotated the cam-wheel t will impart a vertical reciprocating movement to the rack tu, and the pinion h will be partially rotated, rst in one direction and then in the opposite direction, the arm g being thus vibrated, l

IOO

' as the center ot' the heel always needs more ofthe bored `stud b for the usual stud, and the bolting of the frame n upon the bracket B.

By means of the cam-Wheel t and the mechanism shown the vibrating movement imparted to thejack H isdfterential-t-hatis to say, there is a decrease in the speed of the movement at and near the mid-position, so

that the burnishing-tool acts for a longer time upon the hollow or center of the heel than upon the top or bottom of the same, this being in accordance with the requirements of the case,

burnishing than the other portions.

The use ofthe peculiar heart-cam shown is not vnecessary for accomplishing this differential movement, however, as a plain cam, acting through the medium ot' differential gearing, will effect 'the same result.

We claim as our inventionl. The coinbination of the shoe-carryingjack H of the machine, the tool-carrying shaft, and the lever F for operating the latter, with a rod, d, connected to the jack and passing through the stud on which the lever F vibrates, as set forth.

2. The combination of thejack H, the toolcarrying shaft, and the lever F, with the rod 61 passing through the stud on which the lever vibrates,and a frame, m n, secured to the bracket B of' the machine and carrying the mechanism for operating the rod, whereby the ready adaptation of the attachment to the machine is effected, as set forth.

3. The combination of the tool-carrying shaft and the jack H with mechanism, substantially as described, for imparting a differential Vibrating movement to said jack, as set forth.

4. The Within-described jack-operating attachment, comprising the rod d, frame m u, shaft 7c, with worm-Wheel s, and cam-wheel t, rack w, pinion h, arm g, and spindle carrying the Worm o and driven Afrom the main shaft-jl D, as set forth. -f
